Mains Voltage Stabilizer Circuits These circuits were drawn for a person in Africa. See the thread here… stabilizer circuit. They were not tested by me, but are quite close to a practical design. Stabilizer Step up 230V AC 500VA This circuit is a design i did, not tested by me as yet. It can Stabilize Mains voltage to around +/- 10% . It can be used for both 110V AC or 220V AC inputs with modifications. The Output is 220V AC. There is an overload, under voltage and over voltage trip circuit. With some tweaks and modifications it might work. [Read More ....]
These are documents and circuits which will help learn Basic Temperature closed loop control, There are many ways to control temperature. ON-OFF Hysteresis or Dead Band Control. Proportional Control with Reset. Full PID Control, Manual and Auto Tune. The first one is an electronic emulation of Thermostat or Electro-Mechanical Controls. The second is a Time-Proportional like a slow PWM. The third is the complete adaptive control. While the first is like a limit switch, the second works like a SMPS, the third PID takes into account the speed of the process and dynamic changes or disturbances of the system and [Read More ....]
